My reply is almost always: life isn't a fairy tale. Some of us will remain single having never found/taken the opportunity to meet someone who wants to be with us because all life is without intrinsic meaning or purpose.

We may create our own meaning or purpose, but there is no part of life that is written in stone that simply "will be because it is ordained."

I know who I am, an extremely "acquired taste," who is often too cynical and very very much self loathing. Above all else though, and probably worst of all for my dating prospects, I never want to live with a dog lol
